74LVC16374A; 74LVCH16374A
16-bit edge-triggered D-type flip-flop; 5 V tolerant; 3-state
[1] All typical values are measured at V

allowing 5.5 V on the input pin.
[3] Valid for data inputs (74LVCH16374A) only; control inputs do not have a bus hold circuit.
[4] The specified sustaining current at the data inputs holds the input below the specified V
I
level.
[5] The specified overdrive current at the data input forces the data input to the opposite logic input state.
